Modeling A
==============

Characteristics of modeling
-----------------------------------

Characteristics of the bay:

:math:`A=2.24E–3{m}^{2}`; :math:`{I}_{y}={I}_{z}=3.7E–6{m}^{4}`; :math:`{J}_{x}=7.4E–6{m}^{4}`; :math:`{A}_{y}={A}_{z}=1.2`

Characteristics of the posts:

:math:`A=3.14E–2{m}^{2}`; :math:`{I}_{y}={I}_{z}=4.5E–5{m}^{4}`; :math:`{J}_{x}=9.0E–5{m}^{4}`; :math:`{A}_{y}={A}_{z}=1.2`

The analysis focuses on :math:`0.5s` in 100 equal steps of time.


Characteristics of the mesh
----------------------------

The span is modelled by 12 beam elements; each column by 2 elements. All of these elements are :math:`\mathrm{1m}` in length.
